About Dr. Andrew Neville


“Adrenal Fatigue may be an ‘invisible condition,’ but I know it’s real, life-changing, and sometimes debilitating.”


Let me first say, I am a graduate of Bastyr University School of Naturopathic Medicine and am a licensed Naturopathic Doctor. I am not an internet “doctor,” as are some of those who claim to treat Adrenal Fatigue through quick-fix programs. Adrenal Fatigue is my only area of expertise and has been for 16 years.

Nestled in the quiet countryside of Quakertown, Pennsylvania, Clymer Healing Center stands as the physical embodiment of a half-century commitment to provide recovery and care for patients with Adrenal Fatigue.

Clymer Healing Center has helped:

  • 12,000+ Patients
  • In 52 Countries
  • On 6 Continents
  • Since 1969

No one can claim this track record or hands-on experience with patients.

In the video below, I share my personal reflections on the health battles that led me to Clymer Healing Center.

I can help … no matter where you are.

My patients are nationally and internationally based. In 52 countries since 1969, Clymer Healing Center has learned a great deal about Adrenal Fatigue treatment, even from afar. We are at the forefront of the assessment and treatment of Adrenal Fatigue.

I have benefited from my predecessors’ decades of experience, and I continue to improve upon and refine their protocols. Every day for the past 16 years, I have had consultations with thousands of patients in one of three ways:


If you know (or strongly suspect) your adrenals are the real source of health problems, I’m so happy you found me.

What’s at the root of your debilitating fatigue? These articles are a good first step on your path to education and healing:

The first thing I always say to my patients is, “None of this is your fault.”

They’ve seen a parade of specialists, endured countless tests, and yet, they are no better. No one seems to know how to help them, and they begin to think they’re doing something wrong.

It’s exhausting, mentally draining, and it forces them to live inside a whirlwind of stress and anxiety. They never seem to be able to find relief.

If this sounds all too familiar, I have one more important message for you: It’s not all in your head.

I know you’re skeptical. I know you’ve been on the specialist merry-go-round. Many of my patients find me after having been mistreated and mishandled by other “adrenal specialists,” internet personalities, or the mainstream medical establishment.

Mine is a holistic approach to healing, encompassing all areas of your life and all bodily systems. You must be treated as a whole person and not as a cluster of symptoms to be “picked-off” by specialists, one by one. We must get to the root cause.

I am, first and foremost, compassionate. I get it. In fact, most of my staff has been where you may be right now, and as you saw in the video above, I suffered from my own battle with Adrenal Fatigue.

Clymer Healing Center’s singular study of Adrenal Fatigue has shown me the most important element of healing: finding the root cause of the debilitating fatigue, the thyroid and digestive disorders, the insomnia and depression.

Unless the Adrenal Fatigue is addressed, true and lasting relief is not possible. Healing is not done by way of a “cookie-cutter” approach, but rather through an individualized  protocol. It’s what works.

Even if it seems unattainable to you right now, you truly can get your life back and start to live again.

  • I was a Hairstylist with a successful business and active lifestyle. I had an accident that caused a back injury in 1998 and this is where my journey begins. Because I was healthy prior to this accident I didn’t have much experience navigating through the medical world. I followed all the doctor’s orders, taking thyroid medications, hormones, etc. When the standard medical treatments didn’t work, and actually made me worse, then came the suggestions of anti-depressants.

    I didn’t want to take the anti-depressants because I didn’t feel this was the problem. I was sad because of the decrease in my quality of life, I was angry that I couldn’t get anyone to help or get to the route of the problem, but I wasn’t depressed.It was hard to remember what it felt like to not struggle to get out of bed every day, to not be in pain every day, to remember me, the real me.

    After spending 20+ years, thousands of dollars on hundreds of medical tests, doctor visits, inpatient hospital stays, and emergency room visits, being misdiagnosed and misinformed, I found Dr. Neville and Clymer Healing Center.

    I’ve been with Dr. Neville and Clymer Healing Center for 6 months and I’m seeing and feeling incremental improvements. I’m learning things each week and am feeling stronger.I still have a ways to go but for the first time, in a very long time, I’m hopeful.

    My only regret it that I didn’t find Dr. Neville sooner!

  • Hi, I am suffering from severe insomnia and have seen many specialists all of which can’t seem to figure out what is going on and why I can’t sleep. In addition, I’ve experienced weight loss, anxiety and also have RLS which doesn’t help sleep. I have resisted sleep meds as they don’t work long term. Does this sound like adrenal fatigue?

  • Hi Clymer. I have chronic Lyme disease. Is there an article that I can read about how the adrenals affect it? Heard they do from a chiropractor friend in IL, but I haven’t been able to find anything anywhere. Thx, Marcie

  • Dr. Neville,

    I am convinced I have later stages of adrenal fatigue with some symptoms in stages 3B, 3C, and 3D. The biggest downfall right now is the catabolic state my body has been in for about the last 2 months as I’ve seen muscle loss in my quads, some in my calves, and in my biceps. Are you able to help reverse the catabolic state that Dr. Lam talks about?

    Thank you,
